Same-Day Session Store Rescue
Recent work · B2B SaaS platformPassword resets could not sign out active sessions — the legacy platform kept no server-side session state — and sticky sessions pinned every user to one server.
Shipped a database-backed login-token check the same day, then hardened it into a Redis session store and removed the session-affinity constraint.
🎯 Fixed for all customers — and cut application servers from 12 to 7 while serving 700+ customers.

Mobile Unification on Flutter
Recent work · B2B SaaS platformSeparate native iOS and Android apps — one developer each — meant duplicated fixes and diverging logic.
Proposed and won approval to converge both apps into a single Flutter codebase, transitioning key engineers into migration leadership.
🎯 One codebase, one mobile team — and critical domain expertise retained.

Global Build Infrastructure on GCP
Motorola Solutions · Cloud InfrastructureAndroid builds ran on legacy infrastructure — one sequential build at a time, each taking 5–6 hours.
Rebuilt the build infrastructure on GCP with on-demand agents: each build spawns its own server, up to 10 running concurrently, destroyed when the job completes.
🎯 10× build capacity with zero idle cost — alongside cost governance that consolidated five non-production App Service plans into one, an 80% reduction in plan count.

WAVE Apps Takeover & Expansion
Motorola Solutions · Mobile Radio ConfigurationThe WAVE configuration apps arrived as a US product transfer supporting only one radio model — the TLK 25.
Took full ownership with the Penang team and extended coverage across the remaining TLK models.
🎯 Full TLK family coverage, including the TLK 110 — the product grew rather than just being maintained.

Monolith to Microservices
Seagate · Platform RedesignA legacy US-based monolith limited scalability and made data consistency across features hard to guarantee.
Led the development pod decoupling the monolith into Golang and PostgreSQL microservices — Saga pattern over NATS.io pub/sub for distributed transactions, a custom RBAC system modeled on AWS IAM, and automated CI/CD with Jenkins and Kubernetes.
🎯 Transitioned to a highly scalable microservices architecture and shipped the platform's complex subaccount model to production.
